The invention relates to the use of methyldiethanolamine as a grinding aid for cement, and in particular its use as a strength enhancing grinding aid for cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration).

The computer simulations show that the effective- ness of grinding aids depends on the mineralogy, OH - i.e. the percentages of the different phases. This is one of the reasons why, depending on the cement, grinding aids do not always have the same effect. Grinding aids reduce the agglomeration energy in all cases.
